Choose Your Cover Fabric
7 oz. Polyester — Our entry-level marine cover fabric, woven from 100% polyester fiber at a 7 oz. per linear yard weight. This lighter option keeps the cover manageable for solo handling while still delivering reliable protection against sun, rain, and debris. Backed by a 3-year fabric warranty. Ships in Black.
9 oz. Polyester — Step up to our heavy-duty polyester, engineered at 9 oz. per linear yard for boats that face tougher conditions or extended outdoor storage. The denser weave adds an extra layer of defense against abrasion and weather without adding unnecessary bulk. Protected by a 5-year fabric warranty. Ships in Navy or Black.
Sunbrella® — For boaters who want the best, our Sunbrella covers use 100% solution-dyed acrylic — the same fabric trusted by marine professionals worldwide. Naturally resistant to fading, mold, and water damage, Sunbrella holds its color and integrity season after season. Covered by a 6-year fabric warranty. Ships in Black, Smoke, or Marine Blue.
Both polyester options feature solution-dyed construction, where pigment is infused into each fiber during production rather than applied to the surface afterward. This process locks color deep into the material, preventing any dye transfer to your boat’s gel coat or finish. The result is a cover that stays vibrant without bleeding or rubbing off. Our polyester is also designed to breathe — it allows moisture trapped underneath to vent out naturally, reducing the risk of mildew and keeping your boat dry. The fabric holds its form without sagging or stretching over time, stays lightweight enough for one person to handle, and stands up to prolonged UV exposure and harsh marine weather.
*The warranty periods above are provided by the fabric manufacturer and cover the material itself. For details on what’s included in the warranty for your completed cover, please see our warranty page.

Frequently Asked Questions
Whaler built a classic Outrage 18 from 1981 to 1989 (18'6", 7'2" beam) and a later, wider Outrage 18 in the late 1990s (about 18'4", 8'3" beam). The two need different covers, so please send us your year and a photo before ordering and we'll confirm the fit.
The classic Outrage 18 hull was renamed the 19 Outrage around 1990 and sold as the 19 Outrage II from 1992 with a redesigned interior and taller console. Tell us your exact model name and year so we can match the pattern.
Some classic Outrage 18s were rigged with twin engines on the full-width transom notch. Let us know when you order so we can confirm the stern fits your setup.
Choose 9oz solution-dyed polyester (Navy or Black) for heavy-duty everyday protection, or premium Sunbrella acrylic (Marine Blue, Black, or Smoke) for maximum UV resistance and longevity.
No. The cover is made to protect your boat while it is parked on its trailer, up on a lift or in storage. Take it off before you tow: trailering with the cover on can damage it and voids the warranty.
Materials and workmanship are covered for 1 year, and the fabric carries its own warranty (5 years on 9oz and 6 years on Sunbrella). Every cover is made to order, so please allow 1–3 weeks; shipping is a $30 flat rate within the continental US.
Pricing: 9oz $835.00 · Sunbrella $985.00 — your final total appears below as you build your cover.
⏱️ Current lead time: 1–3 weeks — every cover is custom-made for your boat.

Boston Whaler 18 Outrage Center Console Boat Cover — Custom-Fit for the Whaler 18 Outrage — Confirm Your Generation
The name Boston Whaler 18 Outrage covers two quite different boats. The classic Outrage 18 (built 1981–1989, then renamed the 19 Outrage) is 18’6″ long with a 7’2″ beam, about 1,250 lb dry, a 63-gallon integral tank and a full-width transom notch for single or twin outboards up to 150 hp, with a center console, plexiglass windscreen and two swivel seats. The later Outrage 18 sold in the late 1990s (listings we found are 1998–2000) is a wider, heavier boat: about 18’4″ overall with an 8’3″ beam, roughly 2,500 lb dry, a 90-gallon aluminum tank and a 20° deep-V hull, laid out with a lockable console, sliding helm and companion seats, port and starboard quarter seats, in-deck fishboxes and an integral swim platform. This Center Console cover is patterned for the 18 Outrage without a T-top, and like all of our Boston Whaler boat covers, it’s cut to the hull rather than a generic 18-foot size chart — so please confirm your year before ordering.
How It Fits the 18 Outrage
The cover peaks over the console and windscreen, slopes over the seating and the bow to the gunwales, and continues aft over the outboard as one drape, closing at the stern. Because the two Outrage 18 generations differ by about a foot of beam, a cover cut for one will not sit right on the other — which is why we ask for your year and a photo on this model. Installation takes about five minutes: drape it bow to stern, run the hem cord along the rubrail, and cinch the adjustable strap-and-buckle tie-downs. It’s made for storage on a trailer, lift, dry stack, or jet dock — take it off before towing, since trailering with the cover on can damage it and voids the warranty.
Not the Same as the 180 Dauntless or 190 Outrage
Whaler’s later 18- and 19-foot center consoles — the 180 Dauntless and the 190 Nantucket/190 Outrage — are newer designs with their own patterns. If you’re not sure which version you have, send us your year (the hull ID number on the transom shows it) and a photo before ordering.
Fabric, Warranty & Shipping
Choose 9oz solution-dyed marine fabric for heavy-duty everyday protection (5–7 year service life) or premium Sunbrella acrylic for 8–10 years of fade resistance. Both are water-repellent, breathable, mildew-resistant, and double-stitched at the seams. Each cover is backed by our warranty (1 year on materials and workmanship, plus 5 years on 9oz and 6 years on Sunbrella) and ships for a $30 flat rate within the US — every cover is made to order, so please allow 1–3 weeks. For the newer 19-footer, see the Boston Whaler 190 Outrage cover, or the Boston Whaler 18 Dauntless cover.
